Youth team games in England can get pretty feisty at times. With so many young guys trying to prove a point on the pitch, a bit of ill-discipline is basically inevitable.

Still, by "a bit of ill-discipline" we mean the odd naughty tackle or an occasional bit of chest-shoving. We do not mean two entire teams - subs and all - charging about at full speed kung-fu kicking each other in their vulnerable bits.

That's not normal anywhere in the world. Well, apart from on this pitch in Brazil maybe.

At the end of this U20s match between Sertaozinho and Flamengo de Guarulhos, things went fully nuclear - only by retreating to an underground blast bunker could anyone have counted themselves safe from these raging footballers.

Apparently Flamengo accused Sertaozinho’s coach of shoving their players, before both sides suddenly started to lay into each other without mercy. After watching this clip, you'll be unsurprised to learn that the referee felt compelled to hand out 11 red cards after the match.

It's possible that these youngsters are just in the wrong sport, of course. The dojo is this way , lads.
